rection of the arrows.

Be it known that I, DENNIS T. IGoU, a citizen of the United States,residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Impovements in Machines fory Forming andrap pin Confections, of which the following is a speci cation, referencebeing had therein to the accompanying drawings.

This invention relates to` wrapping-inachines, and more particularly tomachines for forming and wrapping confections, and has for .its objectto provide a machine designed priniarily for the purpose of taking fromthe mass of candy a portion thereof, subdividing the same to formconfections, and wrapping the confections thus formed in a wrapper opaper or the like, secured by having its projecting ends twisted 1nopposite directions.

More specifically, the object of my invention is to produce a machinewherein these several operations will be automatically performed withcertainty and speed, thereby reducing the cost of preparing thelconfections for the market.

To these ends my invention consist-s in certain novel features, which Iwill now proceed to describe and will then particularly point out in theclaims.

In the accompanying drawings, Figure 1 is a plan View of a machineembodying my invention. Fig. 2 is an end elevation thereof, with thecandy-feeding rolls removed. Fig. 3 is an elevation of one side of themachine.

F i0. 16 is a detail sectional view showing amodification of the twister. Fig. 17 is a similar view showing adifferent position of the parts, and Fig. 18 is a transverse sectionalview of the same.

Considered as a whole, the machine in the embodiment thereof chosen forpurposes of illustration comprises four main groups of mechanism, towit: first, the confectionforming mechanism; second, the conveyingmechanism, whereby the confections are carried to the wrappingmechanism; third, the paper feeding and cutting mechanism, whereby thepaper is fed to the wrapping mechanism and cut to form blank wrappers,and, fourth, the wrapping mechanism proper. These several groups, whichconstitute the machine, are supported upon a bed or table 1 and aredriven by means of a belt from any suitable source of power, passingaround a pulley 2; secured on'a shaft 3, mounted in suitable bearings 4on the bed or table 1. The shaft 3 carries at its rear end a pinion 5,which meshes with a gear 6, from which most of the moving parts of themachine derive their motion. This gear is secured onthe rear end of ashaft 7, extending longitudinally of the machine some distance above thebed 1 and supported at its ends in uprights or brackets 8 and 9,Varising from the bed of j the machine at the rear and front endsthereof, respectively.

Confection-forming mechanism-I will first refer to theconfection-forming mechanism,

the .functions of which are to draw the candy 4A from a batch oiifmass,form it into a bar and feed this bar forward, severing it intermittentlyto lform the eonfections. This mechanism receives its motion from thegear 6, which is provided on its front face with a gearsegment 10, whichmeshes with a gear 11 on a longitudinal shaft 12, mounted in suitablebearings 13, arising from the .bed 1. The shaft 12 thus has anintermittent rotary IOO l the knife is .provided with motion to theextent of one complete revolution at each movement. Said shaft 12carries an arm 14, provided with ra single tooth, which meshes with agear 1'5, secured on a stud-shaft 16, projecting from the front face ofthe upright 8, said e'ar 15 being an idle gear, which meshes, wit a gear17 on a longitudinal shaft 18, provided at its forward end with abevelear 19.

The candy-fee ing mechanism comprises, preferably, two pairs offeed-rollers 20 and 21, mounted on shafts 22 and 23, res ectively, saidshafts being carried in a bracket-frame 24. The number of feed-rollersmay be varied. The upper shaft 23 is provided at one end with abevel-gear 25, which meshes with the bevel-gear 19 and at its other endis rovided with a gear 26, which meshes witlh a corresponding gear 27 onthe lower shaft 23. A side shaft 28, supported from the bracket-frame24, is provided with a bevel-gear 29, meshing with the gear 25 and witha bevel-gear 30, meshing with a similar ear 31 on one end' of the uppershaft 22.

The other end of said shaft 22 is provided with a gear 32, which mesheswith a similar gear 33 on the lower shaft 22. In this way the two pairsof feed-rollers have an intermittent rotary motion imparted to them.

The first pair of feed-rollers 20 are located adjacent to aspinning-table 24, on which a batch of candy (illustrated at 35) is keptin a suitable condltion for working by the usual provisions for thatpurpose. A trough-like conduit 36 extends from the spinning-table tothefirst pair of feed-rolls, and a similar trough-like conduit 37 islocated between the two pairs of feed-rolls. A third trough-like conduit38 extends from the second pair of feed-rolls to an opening 39 in theupright- 9.

Immediately back of the upright 9 and working along the rear facethereof is a knife or cutter 4,0, which is moved past the o ening 39 atintervals by means of the folllowing mechanism. The gear 6 carries agrooved cam 41, in which 4lies the rear end of a lever 42, pivotedbetween its ends at 43 to a support 44. The forward end of this lever isslotted, as indicated at 45, to receive a roller 46, carried by arms 47,extending, upward from a vertically-moving plunger 48, travel'- ing insuitable ways on the rear face of the upright 9. This plunger carries abracketarm 49, in which is mounted a pinion 50, which meshes with afixed rack 51 on .the side of the upright 9, so that. as theplungerdescends and ascends an intermittent reverse movement of rotationis imparted to the pinion 50. One end of the knife 40 is eccentricallypivoted on the front face of the pinion 50, as indicated at 52, whilethe other end of a projection 53, preferablyinthe form of a roller,traveling in a cam-slot. 54,formed in a plate 55, attached to the sideofthe upright 9. By reason of this construction a downward diagonalmovement is imparted to the knife past the open- 39 in the upright.

n practice a portion of the batch of candy lyin on the spinning-tablewill be drawn or wor ed toward the edge thereof and along the trough 36to the first pair of feed-rolls 20. These rolls, in conjunction with thesecond pair of feed-rolls 21 and the troughs or conduits 37 and 38, willfeed the candy forward intermittently, at the same time sha ing it intothe form of a flattened bar. T e end of this bar will be projectedthrough the opening 39 at each feeding movement to an extent sufficientto provide material for the desired confection, and after said end isthus projected the knife 40 will descend and will sever the projectinend with a draw-cut, and thus complete t e formation of the confection.The knife will then ascend and the bar ofcandy will be fed forward asbefore.

Confection-conveying mechanism--Refer ence will next be made to themechanism whereby the confection is carried from the point where it isformed to the point where 1t is wrap ed. This .latter poi-nt liesimmediately be ow the former point, and the vertically-movable plunger48, hereinbefore referred to, and its associated mechanism constitutethe means whereby the confection is conveyed from one point to theother, said mechanism being alded by gravity. The plunger is hollow andhas in its front wall an opening 56, on each side of which isA located aguide-arm 57, ivoted at 58 to the rear face of the front waliof theplunger and-extending above the pivot, its up vided with a pin 59, whicengages a camslot 60 in the upright 9. The centerin and guiding arms 57thus extend vertical y on each side of the opening 56, through which theconfection passes, said arms determining the two sides of the paththrough which the confection moves through the plun er. The cam-slots 60are so constructed t at these er end being pro- 'guiding and centeringarms approach each other after the passage of the confection by gravityfrom the receiving-plate to the delivering-plate, hereinafter described,and thus insure its final placing on the deliveringplate in aproperly-centered osition.

The receiving-plate is indicated at 61. and is carried by an arm 62,secured to a shaft 63, mounted in bearings 64 on the upper end. of aplate 65, fastened to the rear open face of the-plunger. The plate 65has an'opening 66, through which the receiving-plate 61 may be projectedto receive `the confection. The shaft 63 is provided with a spring orsprings 67, which tend to throw the receiving-plate 61 outward out ofthe path of the confection, as shown, for instance, in Figs. 8 and 10.Said shaft 63 is provided at one end with an arm 68, in the ath of whichlies a fixed cam IOO IIO

69, secured to t e rear of the upright 9. The a 3o construction of thecam 69 is such that when the plunger is in the upper portion of itstravel the receiving-plate 61 1s withdrawn, as shown, while during thelower part of the travel of the plunger said receiving-plate isprojected into the interior of the plunger so that its forward edge liesadjacent to the rear face of the front wall of the plunger.

The delivering-plate is indicated at 7 0 and is a flat plate similar tothe receiving-plate 61 and carried by an arm 71, projecting from a shaft72, mounted in bearings 73 on the rear edges of the side plates of theplunger. The shaft 72 is provided with one or more springs 74, whichserve to hold the delivering-plate 704 normally vin the position shownin Fig. 8. Said shaft 72 is rovided at one end with an arm 75, to whic 1is pivoted one end of a link 76, which link is provided at its other endwith a pin or projection 77, which travels in a slot 78 in a iixed plate79, secured to the upright 9. The deivering plate 70 maintains theposition shown in Fig. 8 throughout the travel of the plunger7 exceptduring the period when the plunger is moving over the extreme lowerportion of its path. At this time the pin 77 strikes the lower end ofthe slot 78 and the delivering-pl ate swings downward and outward to aposition outside of the plunger. The construction and arrangement ofthese parts is such that when the plunger has reached the downward limitof its motion and the confection has been cut from the bar of candy in'the manner hereinbefore described the receiving-plate 61 is projectedinward within the plunger, so as to lie below the opening 39, and saidreceiving-plate receives the confection after it has beenl thus cut off.The plunger then rises, and the dey livering-plate 70 is moved inwardand upward into the plunger in position to receive the` confection,which is now being carried upward bythe receiving-plate. ing-plate .Y isthen swung outward by the mechanism described, so as to discharge theconfection and permit it to fall by gravityl upon the deli vering-plate.The front wall of the plate 65, through the opening in which thereceiving-plate is withdrawn, insures the stripping of the confectionfrom the receiving-plate as it is being withdrawn and prevents it fromsticking to the same. After the fall of thev confection from thereceiving to the delivering plate the guidingand centering arms 57 moveinward toward each other, so as to engage the confectionafter its falland insure its being properly centered on the delivering-plate. Theplunger then reverses its direction of travel and moves downward,whereupon the receiving-plate again moves into position to receive thenext confection, and as the plunger approaches its downward limit ofmotion the delivering-plate is Withdrawn to permit the confection tofall by Said receiv-v gravity downward throu h the open lower end of theplunger onto t ie wrapper, which is ready to receive it. In order toinsure the stripping of the confection from the delivering-plate andprevent it from sticking on said plate, stripping devices are provided,consisting of slots 80 in the plate 70 and fixed arms 81, which passthrough said slots as the plate is withdrawn from the plunger. The arms81 are carried by a cross-bar 82, secured to the rear edge of the sidesof the plunger. This construction is shown more particularly in Figs. 8and 12, and it will be seen from these figures that when the plate 70 inswinging downward and outward passes the plane of the rear wall of theplunger any confection adhering to the inner face of the plate will bestripped therefrom by the fixed arms 81.

As a further means for insuring the delivery of the confection from theplunger onto the wrapper I provide an e'ecting-arm 83, secured to theshaft 72 an standing normallyin an upright position within the plungerout of the path of the confection, as shown in Fig. 8, vv'As thedelivering-plate swings down and out this ej ecting-arm swings downwardand inward along the path of the confection, and in case this latter hasany tendency to stick to the interior of the plunger or to thecentering-arms 57 said ej ectingarm will detach it and insure itsdischarge. 'Y

Paper feeding and cutting mechanism. The wrappers in which theconfections are inclosed are formed from a continuous strip of papersupported at one sideof the machine in the form of a roll, from whichthe paper is drawn intermittently, suflicient paper being drawn out ateach operation to form a single wrapper, and after this paper'is drawnhorizontally and laterally across the machine, so

as to lie in the path of the plunger and below I the same, the wrapperis cut off. What is mation of the initial fold. Referring to thisportion of the mechanism, 84 indicates a roll of paper supported on anaxis 85, journaled in blocks 86, adapted to slide in verticalways 87 instandards 88, located at one side of the machi The vertical movement ofthe blocks, 6 is to compensate for the decrease in thediameter of theroll as the paper is drawn from it, and saidvertical movement iscontrolled by spiral cams 89, carried by a shaft 90, mounted in thestandards 88 and provided with a hand-Wheel 91, by means of which saidshaft may be readily rotated. The bearing-blocks 86 are provided withprojections 92, which rest upon the cams 89.

The paper-roll 84 rests upon the shaft 91, and the pa er strip(indicated at 93) is drawn horizontal y from the bottom of the roll andpasses thence to the creasing or breaking de- IIO IIS

. der it, the roller 96 forming a bed or resistance to render saidpressure effectual. By this means the stri of paper has its fiber brokenlongitudina ly, so as to insure its bending properly and evenly underthe operation of the folding devices.

The paper passes from the creasin -rollers 97 to a supporting-plate 101,over W ich the paper passes and la, y means of which it is held. duringand after the cutting operations. A guard-plate 102 is located above thesupporting-plate'101, and the paper passes through the slot or opening103 between said plates. For the pur ose hereinafter described thesupporting-plate 101 is adapted to yield horizontally in the directionof travel of the paper, and to this end said plate is supported y rods104, which pass through guides or keepers 105, supported by the arms 95and standards 94, and springs 106, mounted on the rods 104, serve tohold the supportingplate 101 normally outward in the position shown,although permitting it to recede.

The feeding of the paper is accomplished by means of a reciprocatinggripper (indicated as a whole by the reference-numeral 107) which seizesthe end of the paper and pulls or draws out a quantity suicient to makea wrapper. This gripper (shown in detail in Fig. 13 of the drawings)comprises a slide or body 108, moving in ways 109 transversely of themachine and lying opposite to the supporting-plate 101 and in line withthe same. The ways 109 are formed on the uper portions of brackets 110and 11.1, arising fiom the bed 1 or from abase-plate 112, securedthereon. The body 108 of the gripper carries at its forward end a fixedjaw 113, over which extends stripper-s rings 114, and

'above this fixed jaw there is ocated a movable jaw 115, secured on ashaft 116," mounted in lugs 117 on the body 108. The shaft 116 isprovided with an upwardly-extending arm 11S, terminating in anantifriction-roller 119, the bottom of said arm being flat and restingon a flat spring 120, which holds the said arm and the movable jaw 115normally in the position shown in Fi 9. j Arms 121, extendmg up from thebrac et 111, support -a cam-bar 122, which lies in the path of the upperend of the arm 118 and serves to o erate the movable jaw of the gripperin t e manner hereinafter described.

A reciprocating motion is imparted to the gripper by means 'of a link123 pivoted at one end at 124 tothe body of the grip er, its other endbein pivoted at 125 to the' forward end of a'v ever `126, which latteris in turn pivoted between itsA ends at 127 to an arm 128', extendingupward from the bed. The lever 126 lies adjacent to theintermittently-rotating shaft 12, and said shaft is provlded on oppositesides of the pivot of the ever with cam-arms 129 and 130, which are adated to strike the lever 126 alternately, saidp lever bein provided withantifrictionrollers 131 am? 132, with which the camarms contact. It willthus be seen that at each revolution of the shaft 12 the gripper Will becaused to travel from its normal position, as shown, across the path ofthe plunger and. back again. During its forward movement the upper endof the arm 118 strikes the face 122a of the cam-bar 122, thereby raisingthe movable jaw 115 of the ipper and opening the' gripper, which is eldopen during the remainder of the forward travel of the grip er by reasonof the contact of the upper en of the' arm 118 with the horizontal undersurface 122b of the cambar. As the gripper approaches with open jaws theend of its forward movement the advance edge of the fixed jaw 113 comesinto contact with the supporting-platelOl and pushes back said plate andits guard-plate, so as to permit the forward edge of the paper, which iseven with the front edge of the supporting-plate, to pass in between thejaws of the Gripper. The arm 118 then passes beyonrll the end lof thecam-bar 122, and the spring 120 throws the arm 18 again into verticalposition. ,The movement of recession of the gripper immediately begins,whereupon the upper end of the arm 118 comes into Contact with the othervertical face 122c of the cam-bar, and the movable jaw 115 is forceddown upon the fixed jaw, so as to grip the free end of the paper. Thejaws are held closed during the return movement of the gri per by reasonof the contact of the upper end) of the arm 18 with. the under surface1.22b of the cam-bar, so that the paper is drawn out during thereceiving movement of the gripper until a sufficient quantity to form awrapper lies across the path of the plunger. When the gripper hasreached the end of its return movement, the arm 118 asses free of thecam-bar and the paper is re eased.

The movable jaw 1 15 of the gripper is provided with a facing, ofrubber, 133, which ives a better hold and prevents the paper fromadhering to the movable jaw. l The stripper-springs 114 lie in grooves134 in the fixed jaws when the jaws are closed,` and when said jaws areopen said stripper-springs rise and prevent adhesion of the aper to thefixed jaw. The pa er is out whiff); still under tension by the pul ofthe gripper, and for this purpose the gripper stops or dwells for a ITOAcam-bar to openthe jaws.

This slot isinclined so as to give the knife a draw cut, in order to moreeffectually sever the paper, the supportingplate 101 acting as aledger-plate to coperatewith the knife during the cut. Motion isimparted to the knife by means of a crankarm 140, to which the rear endof the `knife is ivotally connected, said. crankarm.`being ocated on theend of a shaft 141-, carried in a. slide 142, reciprocating on `twovertical rods'l 143, arising from the bed. Springs 144 on said rodsserve to hold the slide normally in a raised position. 011e. of theguides 143 is provided with a rack 145, with which meshes a pinion 146on the shaft 141, so that vertical movement of the slide 142 will causethe pinion to rotate and thereby operate the knife. Motion is imparted.to the slide by means of a lever 147, pivot'ed at 148 on the support 44.r[he forward end of this lever bears upon the top of the slide 142,while its rear end liesin the path of a projection or roller 149 on themaster-gear 6. The construction is such that the paper is severed duringthe temporarystoppage of the receiving motion of the gripperliereinbefore referred to, so that the cut is made while the paper isunder tension.

In order to insure the positive stoppage of the receding movement of thegripper, both at its momentary dwell and at the end' of said movement,there is secured to the shaft 12 a stop-wheel 12, having in itsperiphery two stop-notches 12b and 12C, adapted to be engaged by adetent-spring 12d, arising from the bed 1. When the pinion 11 is reachedby the blank space 135, the spring 12d enters the notch 12b and stopsthe shaft 12, preventing K overthrow through the inertia of the partsand insuring the temporary stopping of the gripper at the proper point.A tooth 10EL follows the blank space 135 and completes the receding ordrawing-out movement of the gripper, whereupon the spring 12d enters thenotch 12C and positively stops the grlpper at the end of said receivingmovement.

Folding and twisting devices-The blank wrapper having thus been cutwhile it lies in the path of the plunger, is first given an initialfold, which gives it a trough-like or U shape in section. Thispreliminarj, fold is During this moldownwar .end the cam 41, whichoperates the supported from the -accomplished by the plunger inconnection with folding-plates, .which will be nowreferredto. i

The plunger is provided at its` lower end with downwardly-directedneedle-points 150, and said lunger has a preliminary or lmtlal movement,which causes these needle-points to ierce the4 paper while the said paer is st1l under tension and 1mmediate y`before it is cut off. Thedownward movement of the plunger is temporarily arrested during thecutting, and to thls plunger, is rovided with a concentric portion 151,whlch arrests temporarily the movement of the lever 42, which actuatesthe, plunger. After the aper is cut the plunger begins anew its ownwardmovement, carrying with it the wra er, which is forced downward betweenfi) din -plates 152 and 153,

This gives the wrapper a trough-like or U sha e, bending up 1ts frontand rear ends, an the wrapper is carried down Until it frests upon asupporting-plate. 154, which receives the wrap er and the candydeposited thereon by the p unger in the manner hereinbefore described,and holds the same during the operations of folding and twisting thewrapper. The plunger having reached its downward limit and deposited theconfection on the wrapper then recedes, and to v prevent the wrapperfrom following the plunger in its upward motion stripping devices areprovided, substantially as follows: From the folding-plate 153thereoextends downward a stripplng-plate 155,-said' plate being aspring-plate, terminating in an engaging edge or point 156, whichprevents the return of the rear edge of the wrapper. The bracket 0n theother side, or in front of the plunger, is provided with projectionsl57, ony which are ivoted stripper-dogs 158, one on each side o` thefolding and sup-- porting plates hereinafter referred to, as shown inFig. 12. Each stripper-dog is provided with an arm 159, carrying aneedlepoint 160, and with a second arm 161, lying normally in the vpathof. the plunger. A third arm 162, acted on by .a spring 163, serves tohold vthe stripper-dogs in eitheroperative or inoperative position.Normal y these dogs areln the position shown in Fig. 11, so that when'the lunger descends 1t 'strikes the arms 161 an throws the needlepoints166 out into position to engage the paper and prevent 1ts u wardmovement during the return of the p unger. The dogs are held in thisyosition by the springs 163 until after the p unger has been withdrawnand are then subsequently returned to their normal positions before 'theplunger again descends, by means of a cam or cams 164, to be hereinafterdescribed, which operate on arms 165 of said dogsand return them to'tlieroo IIO

Thisblade is projected forwardover the rear portion of the wrapper, so as to insure said rear portion:being properly bent down around the confection, and this projecting of-the blade occurs durin the forward movement of the plate and 1seffected by the'following mechanism: The `blade 1s provided-at its lowerend with an arm 175, to.I vwhich is pivoted the forward end of a 'link176, and the rear end of said link is pivoted to the upper end of alever 177, having a fulcrum between its ends at 178 on a .projection179, extending rearward from the bracket 111. The blade is held normallywithdrawn within the plate by means of a spring 180, having anarm 181,which bears against the front of vthe lower end of the lever 177. As therod 167 advances carrying, the plate and blade with it, the spring 181by its pressure against the -lower end of the lever 177 moves the upperend of said lever to which the link 176 is connected, forward,

so as to maintain the blade in its withdrawn position until toward theend of the advancing movement of the folding-plate. At this point a dogor projection 182 onthe rod 167 comes into contact with the lower end ofthe lever 17 7 and, moving the same forward, withdraws the upper end ofthe lever into the intermediate position shown in dotted lines in Fig.8, thereby movin the blade 173 outward in the arc of a circ e and caus'nit to complete the folding down of. the rear ap of the wrapper aroundthe confection. As soon as this part of the folding operation iscompleted the front edge of the wrapper is folded and suaves over therear edge and around fthe confection by means'of the front folding-plate183,

which is a curved plate similar to the plate 166, but provided with aneedle-point 184 to pierce the wrapper, enter the confection, and f oldthe wrapper and confection firmly during the twisting operation. Thisfoldingplate 183 is secured to the end of a slide-plate 185, slidinglongitudinally ofthe machine on ya su port 186, having a slot 187,through whic asses a pin 188, by means of which the sli i plate 185isconnected with the arm 189, y means of which it is operated,

an arm 193, to which is connected one end of a rod 194, which extends tothe rear of the machine, passing through a suitable guidingaperture 195in the rear bracket 8. The rear end of thisrod lies in the path of a cam196 on the front face of the gear-wheel 6, so that at the proper timethe rod 194 is pushed forward, rocking the sleeve 191 and causing thefront folding-plate 183 to advance. The plate is returned 5to itsposition by a spring 197, actin on the sleeve 191.

It may e here stated that the supportingplate 154 is operated in asimilar manner by a similar cam 196% Said plate is supported in ways 198on the under side of a plate 199, having a slot 200, through whichextends from the plate a vpin 201, which enters a slot 202 in an arm203, extending from a sleeve 204, mounted on the shaft 192 within thesleeve 191. The sleeve 191 is provided near its upper end with a slot oropening 205,

through which there proj ects from the sleeve that the former is firstoperated so that the folding-plate 183 is withdrawn slightly before thesupporting-plate 154. A spring 197 is connected to the arm 203, so as toreturn scid arm and the sleeve 204 to their normal positions after thecam 196a has operated. These operations d`o not take place, however,until after the twisting of the ends of the wrapper, and this twistingis accomplished by the following mechanism: "On opposite sides of thecentral line of the mac me are arranged in axial alinement wlth eachother shafts 209 and 210, supported in bearings 211, arising from thebed 1. On each shaft between the bearings 21 1 is mounted a sleeve 212,connected with the shaft byl vtrolling the rods 194 and 207, are soarranged arrangement which will permit the shaft to slide whilecompellin it to rotate along with the sleeve. Each s eeve 212 is rovidedwith a bevel-pinion 215, which mes es with a similar pinion 216 on alongitudinal shaft 217, having at its rear end a bevel-pinion 218. Thepinons 218 mesh with similar pinions 219 on the ends of a shaft 220,having on its intermediate art a bevel-pinion 221, which meshes wit abevel-pinion 222 on the end of the shaft 3. In this way a continuousrotary motion in opposite directions is imparted to the shafts ,209 and210.

Each shaft is provided with a twister-head comprising a fixed head 223,secured on the end of the shaft, and a sliding head 224, sliding on theshaft, but rotating along with it. The twister-arms 225 are pivoted tothe fixed head 223 and pass out between slots in the sliding head 224,said sliding head having pins 226, which enga e diagonal -slots 227 inthe twisting-arms. he construction is such that when the sliding headsare withdrawn the twistin -arms stand in positions substantially radiato the shaft, and when the'sliding heads are moved forward thetwistingarms move downward into positions substantially parallel withthe shaft. Each twisting-arm is provided with a twisting-finger 228,having a needle-point 229 to engage the paper. Each of thetwister-shafts is normally drawn out or away from the other shaft bymeans of a spring 230, acting through an arm 231 on'a collar 232 on theshaft. The twisters and shafts areadvanced and retracted by means ofcams 233 on the front end of the shaft 7. Each cam 233 has engaged withit the upper end of a lever 234,

operated to advance the twisters the slidingv heads are first advanced,the shafts being restrained by their springs, so that the first movementis a closing movement of the twisting-fingers upon the ends of thefolded wrapper. The sliding heads then continue to advance while theyrotate, carrying along with them the shafts and fixed heads, so thatboth twisters move toward each other as they rotate, and by theengagement of the twisting-fingers and their needle-points with thewrapper the ends thereof are twisted in opposite directions. The advancemovement of the twisters compensates for the shortening of the wrapperas it is twisted.

After the twlsting is completed the twisters recede, so as to releasethe wrapped confection. If this receding movement occurred with both ofthe twisters in"en0'age ment with the wrapper, this latter would betorn, and provision is therefore made\-for causingl one of the twistersto release its grip upon t e wrapper before it recedes. To thls end. theshaft 210 has mounted behind it a vertically-sliding stop-plate 240,carrying a stop-block 241, provided with a recess 242 .to receive theend of the shaft 210, and with an incline 243 to relieve its outwardmovement. This plate is operated by an arm 244, mounted on the shaft236, which is connected with the shaft 210, said arm 244 extendingthrough a slot 245 in the plate 240. 4 The plate 240 is provided with adetent-recess 246, adapted to be engaged by a detent-sprin 247. The'construction of these parts is suc that when the shaft 210 is advancedin the lmanner hereinbefore described the plate 240 is moved upwarduntil the end of the shaft 210 is opposite the recess 242, and at thesame time the detent-spring 247 engages the recess 246 and holds theplate 240 in this position. At the beginning of the return movement ofthe twisters the shaft 21.0 cannot move outward under the impulse of itsspring, being prevented bythe stop-block 241, so that the movabletwister-head member 224 on said shaft moves out first, withdrawing thetwisting-fingers from contact with the wrapper. After this release ofthe fingers the arm 244 strikes the bottom of the slot 245, thelocking-plate 240 is withdrawn, and the twistershaft 210 may moveoutward simultaneously with the shaft 209.

It is obvious that a similar provision might be applied to both twistersinstead of to one only, although this latter is sufficient.

The confection having been thus wrapped, the supporting-plate 154 iswithdrawn by means of the mechanism provided for that purpose, and theconfection is discharged by gravity. It may pass downward through asuitable opening 24S-in the bed and be discharged into any suitablereceptacle. For convenience in operation I provide u on thesupporting-plate 154 the cam 164, w ich by its engagement with the arms165 of the stripper-dogs 158 serves toreturn these latter to theposition shown in Fig. 11, ready to be again operated by the plungeruponits descent. l I

Since the operation of the different mechanisms of which the machine iscomposed has been described in detail in connection with the structuraldescription thereof, it is unnecessary to here repeat the same. It willbe seen, however, that the machine as a whole is adapted to draw thecandy from batch, shape it and feed it forward, cut it up or subdivideit into confections, carry-theseV confections to the wrapping-point,feed forward the paper and cut it into wrappers, fold these wrappersaround the confection,

- ends of t and com lete the operation by twisting the iie wrappers. Thecom leted product of the machine is shown in ig. 15. It will also beseen that these operations are automatically and rapidly performed andthat means are provided for insuring the proper operation of the variousparts of the machine, and provision is made to adapt 1t to the peculiarcharacteristics of the materials on which it operates.

I do not wish to be understood as limiting myself to the precise detailsof construction hereinbefore described and shown in the accompanyingdrawings, as it is obvious that these details may be varied withoutdeparting from the principle of my invention.

n Figs. 16, 17, and 18 I have illustrated a modified form of thetwister-headdesigned to give to the twisted ends ofthe wrapper an openor cup-like form. To this end the twister-shaft 210 terminates at therear end of the fixed head 223, and a mandrel 249 ismounted to slide inthe bore of the fixed head, being connected with the movable head 224 bya in 250, passing through slots 251 in the fiXe head. The rear ends ofthe slots 227 are so shaped that as the movable head advances from theposition shown in full lines in Fig. 17 the mandrel is first projected,as shown in dotted lines, so as to enter the end of the wrapper, and thetwistingfinger subse uently moves down toward the mandrel, hol ing theend of the wrapper on it during the twisting, so that an open or cup-`like form is given to said end, as shown in Fig. 15. The mandrel ispreferably provided with a cover 252, of rubber or the like, and theneedle-points 229 are dispensed with.
